Some more Edentide things, this time some side characters and one (1) antagonist much later down the storyline.
Abel and Adam&Eve are dead, so their souls aren't restricted to how they looked in life and can be whatever they want.
Abel, after suffering a "mysterious accident," decided he would much rather be in the vague shape of his favourite animal. He's a good kid who absolutely didn't deserve the fate he got... but everyone will tell you he's a bit of a smart ass in The Blue.
Adam&Eve decided they didn't like being separated in death, so they decided to occupy the same space as each other in one 'body'. They can unfuse at any point, but would rather not.
Cain is. Well, he's sulking on the Moon these days after being punished with immortality by Mr. Trinity. Might have something to do with killing his brother in a jealous rage, but I guess we will never truly know, eh.
